问题描述

以下是我的HTML页面的代码段:

Below is a snippet of my HTML page:

<td id="Platinum" align="center" width="16%">
    <div></div> 
    <a>link1</a>
</td>
<td></td>
<td id="Platinum" align="center" width="16%">
    <div></div>
    <a>link2</a>
</td>
<td id="Platinum" align="center" width="16%">
    <div></div>
    <a>link3</a>
</td>

在这里,我要选择id ='platinum'的第三个td元素

Here I want to select third td element with id='platinum'

我尝试的是 driver.findElement(By.cssSelector(#platinum:nth-​​of-type(3)));

driver.findElement(By.cssSelector(td [id = 'platinum']:nth-​​of-type(3)));

td with id ='platinum'

推荐答案

code> td 没有ID,这会干扰:nth-​​of-type()计数。选择器意味着 td 元素,而不是nth td 铂'。因此,具有该ID的第三个 td 实际上是整个行中的第四个 td

There is an empty td that doesn't have the ID, which is interfering with the :nth-of-type() count. The selector means "nth td element", not "nth td element with id='platinum'". The third td with that ID is therefore actually the fourth td in the entire row.

使用CSS选择器不能选择第三个具有某个ID的 td 元素。您应该使用XPath:

It's not possible to select the third td element with a certain ID using a CSS selector. You should use XPath instead:

driver.findElement(By.xpath("//td[@id='Platinum'][3]"));
